JSP页面传值乱码过滤方法
本文实例讲述了JSP页面传值乱码过滤方法。分享给大家供大家参考，具体如下：
1.过滤器类：
packagecom.token.t1;
importjava.io.IOException;
importjavax.servlet.Filter;
importjavax.servlet.FilterChain;
importjavax.servlet.FilterConfig;
importjavax.servlet.ServletException;
importjavax.servlet.ServletRequest;
importjavax.servlet.ServletResponse;
publicclassCharacterEncodingFilterimplementsFilter{
publicvoiddestroy(){
}
publicvoiddoFilter(ServletRequestrequest,ServletResponseresponse,
FilterChainchain)throwsIOException,ServletException{
request.setCharacterEncoding("gbk");
chain.doFilter(request,response);
}
publicvoidinit(FilterConfigarg0)throwsServletException{
}
}
2.xml文件配置：
<?xmlversion="1.0"encoding="UTF-8"?> <web-appversion="2.5"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!--过滤器配置--> <filter> <filter-name>CharacterEncodingFilter</filter-name><!--此名字与<filter-mapping>下<filter-name>相同即可--> <filter-class>com.token.t1.CharacterEncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
当我用<form>的默认提交方式提交时，此方法过滤不了，需要设置method="post"，才可以过滤
希望本文所述对大家JSP程序设计有所帮助。
